Polarization-based branch selection of bound states in the continuum in dielectric waveguide modes anti-crossed by a metal grating
We investigate bound states in the continuum (BICs) in a planar dielectric waveguide structure consisting of a gold grating on a dielectric layer with a back layer of metal. In this structure, Friedrich–Wintgen (FW) BICs caused by the destructive interference between the radiations from two waveguid...
